We investigate the interaction of Xe with isolated attosecond XUV pulses. Specifically, we calculate the ion yields and determine the pathways leading to the formation of ionic charged states up to Xe$^{5+}$. To do so, in our formulation we account for single-photon absorption, sequential multi-photon absorption, direct two-photon absorption, single and double Auger decays, and shake-off. We compare our results for the ion yields and for ion yield ratios with recent experimental results…

Mechanisms of 1s Double-Core-Hole Excitation and Decay in Neon

The formation and decay of double-core-hole (DCH) states of the neon ion irradiated by an intense electromagnetic x-ray field are studied theoretically. In the present research DCH formation is the



Observation of nonsequential double ionization of helium with optical tunneling.

A new mechanism is proposed, which can exist only in the tunneling regime, for such nonsequential ionization of helium ionized by 120 fs, 614 nm laser pulses.

Auger cascades leading to higher charged states in xenon driven by an X-ray free-electron-laser pulse

Abstract We study the interaction of xenon with an 850 eV photon energy FEL pulse. We compute single-photon ionisation cross sections and Auger rates by adopting to atoms a formalism we previously

AbstractThe successful lasing at the SLAC National Accelerator Laboratory of the Linear Coherent Light Source (LCLS), the first X-ray free-electron laser (X-ray FEL), in the wavelength range 1.5 to

Multiple photoionisation in the rare gases from threshold to 280 eV

A time-of-flight spectrometer has been coupled with a source of synchrotron radiation to measure the photoionisation cross sections for multiple ionisation of the rare gases He to Xe in the photon
